auth: cephx: KeyServer: add 'has_secrets()' function

We need this in the AuthMonitor to assess if we should encode a full version
of the KeyServer and submit it to the Paxos along with the incrementals.

Not performing such a check will lead us to an erroneous version, from which
we won't be able to recover.
